VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 255,211, dated March 21, 1882.

Application filed December 23, 1881.

To all whom it may concemr Be it known that I, HENRY TIMKEN, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a new and useful Improvement in Buggy-Springs, of which the following is a specification.

My invention relates to side-bar buggysprings where the springs are connected to the side bars at their ends; and the object of my invention is to combine the direct up and down perpendicular spring movement with the twisting spring movements, so as to secure greater strength and at the-same time more elasticity than could be secured by the gse of one alone. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 shows a top view of the device after the buggy-body is removed, with the axle and bolster of the buggy appropriately connected therewith. Fig. 2 represents a perspective view, looking toward the bottom, of my device detached from the body.

Similar letters refer to similar parts through the several views.

Letters A A are two pieces of timber constructed with two sockets, each made to receive the journals on the respective ends of the plates 1) D D l), and provided withbolt-holes to bolt them to the under side of the buggybody; or they may be fastened to the under part of the body in any ordinary way, or mortised into the sills of the body, and be thus a part of it. A A are two other corresponding pieces of timber, made of sufficient size and strength to receive and resist the twisting pressure of the plates D D, &c.

D D D D are long thin plates of springsteel, and are provided at the one end with flat shoulders or arms extending along the under side of the pieces A A, through which there are bolt-holes, by means of which they can be bolted or otherwise securely fastened to the cross-pieces A A, and so as to run at about right angles with them and at the other end they are provided with journals intended to turn in the sockets in the cross pieces A A, as the pressure from the perpendicular spring produces the twisting motion to said plates.

(No model.)

0 c c c are springs having both a downward and upward bend to them-that is, turning downward at first in agradual bend from the large end until it reaches abouttwo-thirds the entire length of the spring, and then gradually turning upward until it terminates under the side bars. These springs are permanently fastened by bolts or rivets to the steel plates D D D D at about right angles with their lateral direction and near the ends of spring is fastened to the opposite plate from where said spring is attached to the side bar, so that the springs always cross each other. In their construction I do not, however, eonfine myself to always making the springs cross from opposite sides.

ff are side bars, supported at either end by the head-block and hind axle, and to them are attached'the springs c c c c by an ordinary shackle.

I am aware that transverse springs pivoted at their middle have been attached to the ends of a longitudinal spring fixed to the bottom of the body by a bolt passing through its center, so that when a weight has been placed upon the transverse springs the longitudinal spring will twist and assist in giving to the body a smooth motion. This longitudinal spring is defective, for the reason that the transverse springs will twist both ends in the same direction, and the probabilities are that it would be torn or wrenched from the bottom if a heavy weight were suddenly brought to bear upon the transverse springs. AIy device differs from that form, in that the transverse springs are attached to separate longitudinal springs, which are rigidly at tached at one end to a bar, A, fixed to the bottom of the body, and pivoted upon a second bar, A, which prevents the springs from sagging when the transverse springs twist the former, thus obviating the objection to the for mcr device, to which I make no claim but What I do claim as new is- 1. In a vehicle, a longitudinal spring rig idly attached at one end and pivoted at the other, in combination with a transverse spring attached by one end to a side bar and by the other to the longitudinal spring at or near the said plates, where the journals are, and each pivoted end,all substantially as described, and for the purpose set forth.

2. In a vehicle, longitudinal springs arranged in pairs, rigidly attached at one end 5 and pivoted at the other, in combination with transverse springs attached by one end to a sidebar and by the other to the pivoted end HENRY TIMKEN.
